Abstract
The invention relates to a tissue monitoring apparatus, a tissue monitoring method and an ablation lesion monitoring, measuring, and controlling automated algorithm incorporating diffuse reflectance spectroscopy (DRS) and/or Arrhenius model thermal denaturation kinetics for determining the characteristics of the lesion or the tissue, especially for identifying the transmurality of the ablation lesion. The invention pertains to a device for and method of real time monitoring of lesion formation as ablation is being carried out.
Claims16
A diagnostic apparatus comprising:
- a catheter comprising an elongated body member having a proximal portion and a distal portion,
- a diagnostic assembly on the distal portion, the diagnostic assembly having a first longitudinal axis;
- wherein the distal portion positions the diagnostic assembly adjacent a first tissue portion such that the first longitudinal axis lies alongside the first tissue portion,
- the diagnostic assembly including:
- an optical emitting element, the optical emitting element configured to emit optical radiation into the first tissue portion,
- an optical receiving element configured to collect optical radiation, the optical radiation indicating characteristics of the first tissue portion;
- wherein the optical receiving element and the optical emitting element are arranged to be spatially offset along the longitudinal axis;
- and
- a processing element electrically or optically connected to the optical receiving element, the processing element configured to process the optical radiation collected by the optical receiving element using spatially offset diffuse reflectance spectroscopy and to calculate a rate of thermal denaturation of the first tissue portion.
